Charge for API access using automatic crypto micropayments

Anyone who calls your automation without paying is blocked, and payment is collected automatically in cryptocurrency before it runs.

How the work actually flows

It repeats. Repeats recheck payment status.

The problem it solves

You have a useful automated service, but there's no easy way to charge people for using it without building a full billing system. Manually invoicing every user for individual calls isn't practical.

Who it fits

Developers or businesses who want to charge for access to an API or automated service without building their own payment system.

How it works

  1. A request comes in to use your automated service
  2. The system checks whether payment has been made in an accepted cryptocurrency
  3. If payment is missing, the request is blocked until it's paid
  4. Once payment clears on the blockchain, the request is processed
  5. The result is sent back to the requester automatically
What you get

Access requests that pay for themselves

Anyone using your API pays automatically in cryptocurrency before their request ever runs.

What you get

A pay-per-use service that only runs after payment is confirmed, with no manual invoicing.

What you need

A cryptocurrency wallet and an account with an onchain payment processing service.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
